Keep in mind that recreating q1 at this stage would give a warning, and try to update the existing qubit to reflect the newly requested parameters: i.e.
In [ ]:q = cl.new_qubit("q1")

T$_2^*$ is usually characterized with a 90-delay-90 experiment where as the Hahn echo removes low frequency noise and that causes incoherent loss and recovers something closer to the true T$_2$. The delay parameter is the pulse spacing and so the total effective delay in the Hahn echo will be 2 times this plus the 180 pulse length.
